In the era of precision cosmology, it is essential to empirically determinethe Hubble constant with an accuracy of one per cent or better. At present, theuncertainty on this constant is dominated by the uncertainty in the calibrationof the Cepheid period - luminosity relationship (also known as Leavitt Law).The Large Magellanic Cloud has traditionally served as the best galaxy withwhich to calibrate Cepheid period-luminosity relations, and as a result hasbecome the best anchor point for the cosmic distance scale. Eclipsing binarysystems composed of late-type stars offer the most precise and accurate way tomeasure the distance to the Large Magellanic Cloud. Currently the limit of theprecision attainable with this technique is about two per cent, and is set bythe precision of the existing calibrations of the surface brightness - colourrelation. Here we report the calibration of the surface brightness-colourrelation with a precision of 0.8 per cent. We use this calibration to determinethe geometrical distance to the Large Magellanic Cloud that is precise to 1 percent based on 20 eclipsing binary systems. The final distane is 49.59 +/- 0.09(statistical) +/- 0.54 (systematic) kiloparsecs.
